3 Claims. (Cl. 15332) This invention relates to new and useful improvements in means for straightening stock such as strip metal, metal tape and the like.

- The principal object of the present invention is to :provide a straightener of the character stated which will automatically straighten strip material as it is payed from a roll.

Another important object of the invention is to provide, a device of the character stated which can be readily mounted for use and which because of its simple'construction has very few parts that might become defective.

Other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawings:

Figure 1 represents a fragmentary side elevational view showing the improved straightener with work passing therethrough.

Figure 2 is a fragmentary top plan view of the structure shown in Figure 1.

Figure 3 is a fragmentary bottom plan view with the stock removed.

Figure 4 is a fragmentary, side elevational view showing a modified form of the invention.

Figure 5 is a top plan view of the structure shown in Figure 4.

Figure 6 is a bottom plan view of the structure shown in Figures 4 and 5.

Figure 7 is a fragmentary side elevational view of a third form of the invention.

Figure 8 is a cross section on the line 88 of Figure 7.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 denotes a stand supporting a roll of metal tape Numeral 1 generally refers to the straightener and this consists of an elongated arm 8 having an ofiset portion 9 suitably secured as at ID to a table or the like II. The outer end of the arm 8 is curved downwardly as at 2 and has an opening 13 therein through which the tape 6 passes.

Inwardly of the openingl3, the arm has a second opening 14 outwardly through which the tape 6 passes in a straightened condition.

As can be seen in Figure 1, secured to the underside of the arm 8 inwardly of the opening I4 is an angular-shaped member l5 secured so that the portion a thereof will assume a substantially horizontal position to define a guide in completing the straightening operation.

Between the openings I3 and M, the underside of the arm 8 has a downwardly and backwardly curved former l6 secured thereto. As

shown in Figure 1, the tape 6 must pass first through the opening l3 and under the curved free end of the former l6 and then along the straight portion a of the angle member It before passing out through the opening M.

A second form of the invention is shown in Figures 4 and 5. In these figures, reference character 8a denotes an arm having openings I3a, Ma therein through which stock Go must pass.

At the underside of the arm 8a between the openings I3a, Ma, a spring former Ilia is secured in place and carries a roller 20 at its free end. An adjusting screw 2| is feedable through the arm 8a and has its lower end bearing in a recess in the former Ilia. or swivelly connected thereto.

Stationary or rotary rolls 22 are provided,

A third form of the invention is shown in Figures '7 and 8, reference character 8b denoting an arm having a curved free end Mb. The arm 8?) has openings I31) and 14b through which stock 6b must pass.

A frame [6b is secured to the underside of the arm 81) between the openings I31) and Nb and a vertically slidable roll 20b. is mounted in this frame I61) and is adjustable by a screw Zlb feedable through the arm 8b regulating the tension of the roll against the stock 6b.

An angle member I5?) is secured to the underside of the arm 81) adjacent the opening Nb and has a straight portion 0 along which the stock 6b must travel, and the upper side of the arm 81) adjacent the opening l4b has a fixed or rotary roll 2217 over which the stock passes. A similar roll 22b is provided adjacent the opening l3b and against which the stock must travel.

Obviously, the arm of any one of the forms of the invention above described may be attached directly to the bolster plate of a punch press or ,to any suitable part of any machine that has strip metal fed thereto. Further, it is preferable that the arm in each of the forms be of spring metal so that the same can be flexed by hand under certain conditions.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. A device for straightening coiled metal tape as it is fed from a roll, comprising an elongated strip-like arm, means to secure one end of said arm to a support so that the arm extends from the support to a point near the roll of tape in the same general direction as that in which the tape is fed, said arm having a longitudinally and upwardly arched free end portion provided with a pair of transverse openings spaced longitudinally of the arm, a flat substantially horizontal guide carried by the arm beneath one opening and extending toward the other opening, and a former attached to the underside of the arm between said openings and arranged to press upon and reversely bend the tape in advance of the guide as said tape passes from the roll downwardly through said other opening then under the former and then over and parallel with said guide and through said one opening in a straight substantiall horizontal path.

2. A strip stock straightener comprising a longitudinally curved elongated strip member having a pair of transverse openings therein spaced longitudinally thereof and through which stock must pass in opposite directions, and a former offset with respect to a plane intersecting the openings of said member and against which the stock must tensionally bear in passing from one opening to the other as it is paid from a roll or other confinement, said former being in the form of a spring finger attached at one end to the strip member and having its other end arranged to bear against the stock.

3. A strip stock straightener comprising a 1011- gitudinally curved elongated strip member having a pair of transverse openings therein spaced longitudinally thereof and through which stock must pass in opposite directions, and a former offset with respect to a plane intersecting the openings of said member and against which the stock must tensionally bear in passing from one opening to the other as it is paid from a roll or other confinement, and an angle member having one end secured to said strip member beneath the second opening through which the stock must pass, the other end of said angle member being straight and extending toward the first opening through which the stock must pass to define a straight guide over which the stock must run in passing to the second opening through which the stock must pass.
